To all whom it may concern I Be it known that I, ALBERTH. BRETT, a

citizen of the United States, residing at Mason City, in the county of Cerro Gordo and State of Iowa, have invented certain ,new and useful Improvements in Devices forj-Djmming the Headlightsof Automo- 'bile's.,; "and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This. invention relates to new and useful improvements in devices for dimming headlights of on-coming automobiles and the primary object'of the invention is to provide a device applicable to any automobile now in use to prevent the rays of light projected from the headlights of oil-coming automobiles from interfering with. the view of-the driver of the machine carrying thls particular device. .Still another object of the invention resides in providing-a device consisting of a. colored glass adjustably mounted on a por.-

tion of thefautomobile and still another object'of the invention. resides in providing a devicewhich is simple and durable in con- .struction, inexpensive to manufacture and one which is very eflicient and useful in operation.

' ith these and other objectsin view, my invention consists in the'novel. features of construction, combination and arrangement an specification and claims. a

In the accompanying drawingforming a part of the specification :Figu're 1 is, an elevation of a device constructed-in accordance'with' myinvention and applied to use. Fig.2 is a section therethroagh with parts arts as will be hereinafterreferred to :.in elevation. Fig. 3 is'an enlarged hOIlzontal section as seen on line 3-.-3 of Fig. 4. Fig. 4 is an enlarged vertical. section through the clamping member used in connection with this device." .F 5 is a .section as seen on line 55 of ig. 4, looking in the direction of the arrows, and Fig. '6 is an enlarged plan view of the gye bolt usedin connectionwith the device? In describingftho' invention I shall re fentothe drawing inwhich similar-meta s.

ence characters designate corresponding more particularly pointed out in the Specification of Letters I'atent. Patntefl Dia 23 1915, Application filed April 16, 19-14. Serial No. 882,282.

parts throughout the several views and in wh1ch- 1 indicates a colored glass disk mounted v in a metal frame 2 and secured to said frame 1n any desired manner 1s a tubular shank or stem 3. This glass disk 1. is preferably amber-colored to enable the eye to observe therethrough without being affected adjustably mounting the same on a particu-. lar portion of the automobile. I desire. preferably to provide a means for securing this device to the wind shield of the machlne and to this end I provide a clamp 4 whlch 1s formed of a pair. of sections 4 and 4 The sections of this clamp are enlarged at the ends thereof and are provided with channels 5 which aline with one another when sald sect ons of the clamp are hr'oi ht together n proper relation to one; anot er whereby to receive therethrough the. shank of an eye bolt 6. A wing nut 7 is engaged with the threaded end. of said eye bolt whereby it will be seen that the sections of Clamp may be drawn together when desired and I have also provided a means for the retention of the eye of the bolt in a predetermined position with respect to the clamp. In carrying out the idea ofthe retention ofthe bolt in a predetermined or adjusted her the one face, the outer face of the section ,4, 1s provided with ratchet teeth Sand a collar 9 isprovided to be received on the position with respect to the clamping memshank of the bolt 6 between the eye thereof 1 and the last mentioned face of the section 4 of said clamp. The bore of the collar is enlarged at diametrically opposite points thereon or otherwise provided with notches.

indicated at 10 and projections are formed on said bolt, which projections are indicated as 11 and received in-the notches or'ofl'sets 7 10 1? said collar It will-thus be seen that -with the rotation'ofthe. bolt with respect to the sections of-the clamp {1, said .collar. will also be rotated therewith. The innerface of .saideollar 9 is providedw ith com-,

plementary ratchet teeth 12 for cooperation' with :the ratchet teeth can" ea outer face-of the section 4. It Will-thus be seen that when the wing nut is turned home to draw the bolt 6 to a position for securing the sections of the said clamp together, the teeth of the collar 9 will securely engage the teeth 8 on the section 4*, thus securing said bolt in any position to which it may be adjusted. The adjustment of this bolt is really for the purpose of adjusting the eye portion thereof with respect to the clamp d, inasmuch as said eye portion receives the shank or stem 3 which is carried on the frame supporting the glass disk. It will thus be seen that after this clamp 4 has been properly applied to the portion of the wind shield convenient therefor, this glass disk may be adjusted to the desired position with respect to said clamp by merely adjusting the eye of the bolt 6 with respect to said clamp. I have also provided a means for the adjustment of the stem or shank 3 with respect to said eye of the bolt. To this end a set screw 15 is provided in connection with said eye and through this medium said shank 3 may be secured in any adjusted position. In view of this particular construction it will be seen that this device is capable of application to any Wind shield or any other portion of the machine convenient therefor and it is also capable of adjustment to suit the convenience of the driver'of the automobile so that said driver may look through this glass disk at times when the rays of light projected from headlights of on-coming automobiles construction of my lmproved device the manner of applying the same to use and the operation thereof will be readily understood and it will be seen that Ihave provided an improved headlight dimmer which is simple and durable in construction, inexpensive to manufacture and one which will be very eliicient and useful in operation.

While I have particularly described the elements best adapted to perform the functions set forth it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to, within the scope of the appended claims, without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described my invention, what I claim is: 1

1.In a device of the class described, a clamping member 'formed in sections, an eye bolt passing therethrough, means engaged with said bolt to secure the sections of said clamping member together, one face of said clamping member being provided with ratchet teeth, and means carried on said eye bolt for engagement with the teeth on the one section of the clamping member,

amassewhereby to retain the eye of said eye bolt in various adjusted positions with respect to the clamping member.

2. In a device of the class described, a I clamping member formed in sections, an eye bolt passing therethrough, means engaged with said bolt to secure said sections together, one face of one of the sections of said clamping member being provided ratchet teeth, a collar carried on the eye bolt adjacent the eye thereon said collar being also provided with ratchet teeth for engagement with the ratchet teeth on the one section the clamping member, whereby to secure the eye of said eye bolt in various adjusted posi tions with respect to said clamping member 3. In a device of the class described, clamping member formed in sections, an eye bolt passing therethrough, means engaged m with said bolt and a portion of said clamping member to secure the sections of the ter together, one face of one section or clamping member being provided T. ratchet teeth, a collar loosely applied to sa eye bolt between the last mentioned face the clamping member and the eye of bolt, one face of said collar being also p vided with ratchet teeth for engagem t with'theteeth on the clamping member, and additional means in connection with the o bolt and said collar for retaining the eye said bolt in various adjusted positions w respect to the clamping member.

4. In a device of the class described, a clamping member formed in sections, an eye bolt passing through portions thereof, means engaged with said bolt and a portion of said clamping member to secure the sections of the latter together, one face of td) one section of the clamping member be) provided with ratchet teeth, a collar loosely" applied to said eye bolt between the mentioned face of said clamping member and the eye of said bolt, the inner periphery of said collar being provided with odsets diametrically opposite points thereon, lugs, carried on said eye bolt received in the off sets of said collar to secure the latter on the bolt, the one face of said collar being also provided with ratchet teeth for engagement with the ratchet teeth of the clamping meraber wherebv to retain the eye of said bolt various adjusted positions with respect said clamping member.
